IMPROVEMENT IN VESSELS FOR CONTAINING LIQUIDS UNDER PRESSURE.

Specification forming part of Letters Patent No. 138,266, dated April 29, 1873 application filed November 26, 1872.

To all whom it may concern.-

Be it known that I, SAMUEL MARKS, of San Francisco city and county, State of California, have invented an Improved Vessel for Containing Liquids under Pressure 5 and I do hereby declare the following description and accompanying drawing are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.

The object of my invention is to provide a substitute for that class of casks which are employed for containing beer, ale, porter, and other liquids under pressure. In cities it is customary for manufacturers of beer, ale, porter, and other beverages to supply families and other consumers with these articles either in five or ten gallon casks or in bottles. In the former case it very often happens that the consumer does not desire a full cask, so that a large portion of its contents becomes stale and unfit for use before it is consumed. In the latter case the impossibility of recovering all of the bottles thus distributed requires that the manufacturer shall demand a higher price for his beverage to cover their loss, besides corks, labor, 8tc. My invention contemplates the avoiding of these difficulties by providing strong earthenware, glass, or other closed jars or vessels of various sizes, varying from one to ten gallons in capacity, and in providing said closed jars or vessels with a cock or faucet at or near the bottom or lower end, and by means of which the liquid under'pressure which the jar contains can be drawn off at pleasure without removing a cork or otherwise disturbing the vessel.

My invention consists in a novel and use ful combination of an arrangement for closin g the upper end of these jars or vessels after the liquid has been placed in it, with a cock or faucet at or near the bottom, by which the liquid can be drawn off, which improvement can also be applied to barrels, casks, and other vessels containing a liquid under pressure.

Inorder to more fully illustrate and explain my invention, reference is had to the accompanying drawing forming a part of this specification, in which Figure l is a perspective view of my jar or vessel. Fig. 2 is an enlarged view of the stopper.

A represents a jar or vessel, which is made of earthenware, glass, or other suitable material, and of sufficient strength to resist the internal pressure which it is necessary for them to withstand. The shape of these vessels is immaterial, and they can be made of various sizes to suit the demands of the trade. At or near the bottom of this closed jar or vessel I attach a cook or faucet, B, which will serve as a means of drawing off the liquid without tapping the vessel. The open upper end or mouth of the jar or vessel A I make oblong or oval. The stopper or plug 0, which closes this opening, is also made oval and somewhat larger than the mouth or opening in the vessel A. This plug is constructed with a shoulder, d, on its upper side, upon which a piece of India rubber or other cushion is secured. A standard, e, is secured to the stopper or plug to serve as a means of handling it in placing it in or removing it from the vessel. The stopper or plug is inserted through the oval opening or mouth into the interior of the vessel by turning it sothat the narrow width of the plug will pass through the widest portion of the mouth, the standard e serving as a handle by which to hold and insert it. After the stopper has been inserted it is turned so that the upper edge of the cushioned shoulder d will rest against the under edge of the opening. A bridge or cross plate, f, is then laid across the opening so that its ends rest upon the opposite edges of the mouth, and a set-screw, 9, passed down through a hole in its middle and screwed into a tapped hole in the center of the plug beneath, so as to draw the plug or stopper firmly against the under edge of the opening. By this arrangement the internal pressure which is generated inside of the vessel will press upward upon the plug and make a tight joint, which will not leak, while it will be impossible for the plug to be forced out by the pressure within. This arrangement is also applicable to barrels and casks v in which such liquids are kept.

By employing the jar or vessel above described consumers can be supplied with ale,

beer, and other like beverages in any desired quantity, so that it will be always fresh and palatable, and at the same time at a much less cost than would be demanded for the bottled article; besides, the beer, ale, or other liquid can be drawn through the faucet in small quantities without disturbing the cork or otherwise affecting what remains inside, while, where an ordinarybottle is employed, if any portion be drawn, the entire contents must be used immediately or Wasted.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

The jar or vessel A having the emptyingfaucet B, and with its oblong or oval mouth, in combination with the oblong or ox al plug G, with its shoulder d, the bridge or crosspiece f, and set-screw g, substantially as and for the purpose set forth.

In witness whereof I hereunto set my hand and seal.
